However, they have some key differences: - LQG focuses on quantizing space-time itself, treating it as composed of discrete loops and nodes at the Planck scale. String theory posits that elementary particles are made of tiny vibrating strings, and requires extra spatial dimensions[2]. - The main goal of LQG is to be a quantum theory of gravity, while string theory aims to be a "theory of everything" unifying all forces and explaining particle physics as well[2][4]. - LQG is background-independent - it tries to emerge space-time from the theory. String theory is background-dependent, assuming a fixed space-time framework[2]. - String theory requires supersymmetry, which predicts undiscovered partner particles. LQG does not require this[1]. - String theory has received far more attention and research effort than LQG, and is considered more mathematically developed. An estimated 95% of quantum gravity research falls under string theory[3]. - However, both theories still lack experimental evidence. String theory has issues like the lack of discovered supersymmetric particles, while LQG has not yet shown it can recover smooth space-time from quantized space[3][4]. Some researchers are exploring ways to combine insights from both string theory and LQG. But significant differences remain, and it's an open question whether they can converge into a unified framework[1][3]. More theoretical work and eventual experimental validation will be needed to determine which approach succeeds in describing quantum gravity.
